Motorists have been urged to take extra care in treacherous conditions as snow across much of the UK turns to ice.
Half of the 1,300 scheduled flights at Heathrow were cancelled and some trains and Tube services were also disrupted.
Snow swept down to London and East Anglia on Sunday after covering parts of Scotland, Wales, northern England and the Midlands on Saturday.
